Cisco Cisco IOS Software Release 12.4(4)T 發佈版本通知

CSCsg50202

Symptoms: When a BRI interface flaps rapidly, ISDN Layer 1 detects a link down state, but Layer 
2 and Layer 3 may remain in the active state during the transition. This situation may cause the BRI 
interface to become stuck, and subsequent incoming and outgoing calls to be rejected.

Conditions: This symptom is observed when a cable is pulled out and put back rapidly.

Workaround: Enter the clear interface command on the affected BRI interface.

Alternate Workaround: Enter the shutdown command followed by the no shutdown command on 
the affected BRI interface.

Symptoms: For normal ISDN call and disconnecting the call, a DISCONNECT message will be 
issued. The contents of this DISCONNECT message will be replaced with the one that is explicitly 
configured. This configured message has an invalid facility component and hence the receiving side 
should send facility reject component which is not seen here (missing).

Conditions: This symptom happens with Cisco IOS Interim Release 12.4(12.15)T. This is happening 
only for Interface PRI. This is seen for Cisco IOS Release 12.4 mainline & Release 12.4T.

Workaround: There is no workaround. 

Cisco IOS Release 12.4(6)T6 is a rebuild release for Cisco IOS Release 12.4(6)T. The caveats in this 
section are resolved in Cisco IOS Release 12.4(6)T6 but may be open in previous Cisco IOS releases. 

The following information is provided for each caveat:

Symptoms—A description of what is observed when the caveat occurs.

Conditions—The conditions under which the caveat has been known to occur.

Workaround—Solutions, if available, to counteract the caveat.

Workaround: There is no workaround.

Release 12.3(18). At this time, the RADIUS accounting tickets are not generated.

Workaround: Enter into configuration mode and change the order of the servers under the server 
group.
